“…Boost converters had been built using a variety of control methods in earlier studies. Similar to [10] [11], the boost converter's control was constructed with a PI controller, and the duty cycle approach was used. There are a number of techniques that are often employed in addition to PID controllers, including fuzzy [12][13], adaptive neuro fuzzy inference system (ANFIS) [14], sliding mode [15] and Linear Quadratic Regulator (LQR) controller [16].…”

DC-DC Boost Converter works to produce an output voltage greater than the input voltage. can be used to supply voltage in various systems. To supply voltage to a system, the boost converter works by applying a switch driven by a PWM generator. This paper presents the design of a control system to adjust the amount of duty cycle on a PWM generator. The use of the LQR control system and integral state feedback to control the duty cycle of the DC-DC Boost Converter is proven to be able to stabilize the output voltage. By providing a frequency of 500 Hz with an input voltage of 1.5 Volts and a reference voltage of 7 Volts, the best performance can be achieved, namely settling time at 5.28 seconds and rise time at 2.6 seconds. The expected performance can be achieved by adjusting the system's power supply requirements, such as determining the reference voltage and frequency of PWM generator.
